Children's physical activity and sedentary behaviour in before school care: An observational study.

OBJECTIVE: In Australia, less than one quarter of children aged 5-12 years meet national physical activity (PA) guidelines. Before school care operates as part of Out of School Hours Care (OSHC) services and provide opportunities for children to meet their daily PA recommendations. The aim of this study was to explore factors associated with children meeting 15 min of moderate-to-vigorous-intensity physical activity (MVPA) while attending before school care. METHODS: A cross-sectional study was conducted in 25 services in New South Wales, Australia. Each service was visited twice between March and June 2021. Staff behaviours and PA type and context were captured using staff interviews and the validated System for Observing Staff Promotion of Physical Activity and Nutrition (SOSPAN) time sampling tool. Child PA data were collected using Actigraph accelerometers and associations between program practices and child MVPA analysed. RESULTS: PA data were analysed for 654 children who spent an average of 39.2% (±17.6) of their time sedentary; 45.4% (±11.4) in light PA; and 14.9% (±11.7) in MVPA. Only 17% of children (n = 112) reached ≥15 min MVPA, with boys more likely to achieve this. Children were more likely to meet this recommendation in services where staff promoted and engaged in PA; PA equipment was available; children were observed in child-led free play; and a written PA policy existed. CONCLUSIONS: Before school care should be supported to improve physical activity promotion practices by offering staff professional development and guidance on PA policy development and implementation practices.

Neighborhood racial income inequality and cognitive health.

INTRODUCTION: Neighborhood socioeconomic status (SES) has been linked to dementia, but the distribution of SES within a neighborhood may also matter. METHODS: Data from 460 (47% Black, 46% White) older adults from the Michigan Cognitive Aging Project were linked to census tract-level data from the National Neighborhood Data Archive (NaNDA). Neighborhood SES included two composites reflecting disadvantage and affluence. Neighborhood racial income inequality was the ratio of median incomes for White versus Black residents. Generalized estimating equations examined associations between neighborhood factors and cognitive domains. RESULTS: Neighborhood racial income inequality was uniquely associated with worse cognitive health, and these associations did not differ by participant race. Neighborhood disadvantage was only associated with worse cognitive health among Black participants. DISCUSSION: Both the level and racial distribution of SES within a neighborhood may be relevant for dementia risk. Racial differences in the level and impact of neighborhood SES contribute to dementia inequalities. HIGHLIGHTS: Black participants lived in neighborhoods with lower socioeconomic status (SES) than White participants, on average. Neighborhood SES and racial income inequality were associated with worse cognition. Effects of neighborhood racial income inequality did not differ across racial groups. Effects of neighborhood SES were only evident among Black participants.

Macroergonomic components of the patient work system shaping dyadic care management during adolescence: a case study of type 1 diabetes.

The role of the social, physical, and organisational environments in shaping how patients and their caregivers perform work remains largely unexplored in human factors/ergonomics literature. This study recruited 19 dyads consisting of a parent and their child with type 1 diabetes to be interviewed individually and analysed using a macroergonomic framework. Our findings aligned with the macroergonomic factors as presented in previous models, while highlighting the need to expand upon certain components to gain a more comprehensive representation of the patient work system as relevant to dyadic management. Examples of design efforts that should follow from these findings include expanding existing data sharing options to include information from the external environment and capitalising on the capabilities of artificial intelligence as a decision support system. Future research should focus on longitudinally assessing patient work systems throughout transition periods in addition to more explicitly exploring the roles of social network members.

Work performed by patients and their caregivers is shaped by the social, physical, and organisational contexts they are embedded within. This paper explored how adolescents with type 1 diabetes managed their health alongside their parents in the context of these macroergonomic factors. These findings have implications for research and design.

Awareness and use of the Eat Smart Play Smart resources in Out of School Hours Care services: A staff survey in New South Wales, Australia.

ISSUE ADDRESSED: Out of School Hours Care (OSHC) is an important setting to promote healthy eating and physical activity. Between 2017 and 2018, The Eat Smart Play Smart (ESPS) resources were disseminated to OSHC services across New South Wales (NSW), Australia. The aim of this study was to evaluate the awareness and usability of ESPS to support OSHC healthy eating and physical activity practices. METHODS: All NSW OSHC services (approximately 1700) were invited to complete an online survey to assess awareness and use of the ESPS resources (manual and online modules). Data were analysed using SPSS (Version 29). RESULTS: A total of 393 OSHC staff responded to the survey. Most (75%) had used the ESPS resources. Of the 25% who had not used the resources, 63% indicated it was because they did not receive the manual and 52% were not aware of the resources. Of the OSHC services that knew about the resources, 69% indicated that ESPS contributed to their service's ability to meet the Australian National Quality Standards. Respondents identified additional support was required regarding physical activity educational materials and professional learning. Suggestions for improvements included offering content in different formats (e.g., digital). CONCLUSION: This evaluation identified factors influencing the uptake of the ESPS resources and will inform future interventions for OSHC staff to improve knowledge and practices in healthy eating and physical activity promotion. SO WHAT?: Our findings will support the optimisation of ESPS resources and inform future development of future healthy eating and physical activity interventions in the OSHC setting.

Factors Associated With Provision of Nonbeneficial Surgery: A National Survey of Surgeons.

OBJECTIVE: We tested the association of systems factors with the surgeon's likelihood of offering surgical intervention for older adults with life-limiting acute surgical conditions. BACKGROUND: Use of surgical treatments in the last year of life is frequent. Improved risk prediction and clinician communication are solutions proposed to improve serious illness care, yet systems factors may also drive receipt of nonbeneficial treatment. METHODS: We mailed a national survey to 5200 surgeons randomly selected from the American College of Surgeons database comprised of a clinical vignette describing a seriously ill older adult with an acute surgical condition, which utilized a 2×2 factorial design to assess patient and systems factors on receipt of surgical treatment to surgeons. RESULTS: Two thousand one hundred sixty-one surgeons responded for a weighted response rate of 53%. For an 87-year-old patient with fulminant colitis and advanced dementia or stage IV lung cancer, 40% of surgeons were inclined to offer an operation to remove the patient's colon while 60% were inclined to offer comfort-focused care only. Surgeons were more likely to offer surgery when an operating room was readily available (odds ratio: 4.05, P <0.001) and the family requests "do everything" (odds ratio: 2.18, P <0.001). CONCLUSIONS: Factors outside the surgeon's control contribute to nonbeneficial surgery, consistent with our model of clinical momentum. Further characterization of the systems in which these decisions occur might expose novel strategies to improve serious illness care for older patients and their families.

Fifty Years of Trust Research in Health Care: A Synthetic Review.

Policy Points First, policymakers can create conditions that will facilitate public trust in health care organizations by making creating and enforcing health policies that make exploitative behavior costly. Second, policymakers can bolster the trustworthiness of health care markets and organizations by using their regulatory authority to address and mitigate harm from conflicts-of-interest and regulatory capture. Third, policymakers and government agencies can further safeguard the public's trust by being transparent and effective about their role in the provision of health services to the public. CONTEXT: Trust plays a critical role in facilitating health care delivery and calls for rebuilding trust in health care are increasingly commonplace. This article serves as a primer on the trust literature for health policymakers, organizational leaders, clinicians, and researchers based on the long history of engagement with the topic among health policy and services researchers. METHODS: We conducted a synthetic review of the health services and health policy literatures on trust since 1970. We organize our findings by trustor-trustee dyads, highlighting areas of convergence, tensions and contradictions, and methodological considerations. We close by commenting on the challenges facing the study of trust in health care, the potential value in borrowing from other disciplines, and imperatives for the future. FINDINGS: We identified 725 articles for review. Most focused on patients' trust in clinicians (n = 499), but others explored clinicians' trust in patients (n = 11), clinicians' trust in clinicians (n = 69), and clinician/patient trust in organizations (n = 19) and systems (n = 127).  Across these five subliteratures, there was lack of consensus about definitions, dimensions, and key attributes of trust. Researchers leaned heavily on cross-sectional survey designs, with limited methodological attention to the relational or contextual realities of trust. Trust has most commonly been treated as an independent variable related to attitudinal and behavioral outcomes. We suggest two challenges have limited progress for the field: (1) conceptual murkiness in terms and theories, and (2) limited observability of the phenomena. Insights from philosophy, sociology, economics, and psychology offer insights for how to advance both the theoretical and empirical study of health-related trust. CONCLUSION: Conceptual clarity and methodological creativity are critical to advancing health-related trust research. Although rigorous research in this area is challenging, the essential role of trust in population health necessitates continued grappling with the topic.

When things go wrong: experiences of vaginal mesh complications.

INTRODUCTION: Previous research has suggested that complications stemming from vaginal mesh can lead to life-changing negative physical consequences including erosion and chronic pain. However, there has been little research on the experiences of women who have had complications. This study was aimed at exploring the individual experiences of women who have had vaginal mesh complications and how this has impacted them. METHODS: An explorative qualitative design was followed. Eighteen semi-structured interviews were conducted with women who had experienced complications with vaginal mesh due to stress urinary incontinence and pelvic organ prolapse. The mean age was 52 and the mean time since the mesh was fitted was 8 years (6 had since had it removed and a further 6 had had partial removal), and the mean time since first mesh-related symptom was 10 months. Data were analysed using thematic analysis. RESULTS: Four main themes were identified: perceived impact of mesh complications, attitudes of medical professionals, social support and positive growth. Results showed that participant experiences of their mesh complication were psychologically traumatic, including feelings of increased anxiety and fears relating to suicidal thoughts. Intimate relationships were also affected, with reduced sexual functioning and intimacy stemming from mesh complications. Negative experiences with medical professionals included feeling dismissed, a lack of recognition of their symptoms, and anger towards the profession. CONCLUSIONS: The impacts of vaginal mesh complications were found to be wide-reaching and life-changing, affecting numerous aspects of participants' lives. Greater awareness in this area is needed to provide further support for women experiencing vaginal mesh complications.

The role of self-compassion and its individual components in adaptive responses to dietary lapses.

Dietary lapses (i.e., instances of dietary non-adherence) are common during weight loss attempts, and compromise success in two ways: increasing caloric intake and demoralizing the participant, sometimes leading them to abandon their weight control goals altogether. Efforts to understand and prevent demoralization have received almost no research attention. Self-compassion has high potential to promote adaptive responses to these setbacks because it reframes "failure" and promotes self-improvement. Past research shows that when participants experience a lapse, those practicing higher self-compassion report higher self-efficacy and intentions to continue dieting. The current study extended this literature to examine whether self-compassion in response to a lapse would predict lower likelihood of a subsequent same-day lapse and greater reports of perceived control over weight management behaviors. We also examined whether the individual facets of self-compassion, including self-kindness (treating oneself the way one would a friend); common humanity (the understanding that everyone has struggles); and mindfulness (non-judgmental awareness of thoughts and feelings) are associated with these outcomes. Participants (N = 140) enrolled in a behavioral weight loss trial completed 6 ecological momentary assessment (EMA) surveys a day for seven days. Total self-compassion and each facet of self-compassion individually were all associated with less negative affect after a lapse. None of the self-compassion variables predicted the likelihood of participants reporting a lapse again that day. However, higher total self-compassion and higher self-kindness after a lapse were both associated with greater perceived self-control over weight management behaviors in the hours following. Common humanity and mindfulness, respectively, were not associated with reports of perceived control. Results suggest that self-compassion following dieting setbacks may prevent goal disengagement, and that self-kindness is the facet most strongly associated with adaptive responses to these setbacks.

Review of Dranove and Burns, 2021. Big Med: Megaproviders and the High Cost of Health Care in America.

David Dranove and Lawton Burn's new collaboration Big Med: Megaproviders and the High Cost of Health Care in America provides readers with a comprehensive tutorial on consolidation in United States healthcare markets over the past 40 years. Although the book is most explicitly aimed at those who look around and wonder how we arrived at a healthcare landscape dominated by giants, anyone with a serious interest in the prices of U.S. healthcare will want to have this rigorous and timely treatment on their bookshelf.

The Association Between Factors Promoting Nonbeneficial Surgery and Moral Distress: A National Survey of Surgeons.

OBJECTIVE: To assess the prevalence of moral distress among surgeons and test the association between factors promoting non-beneficial surgery and surgeons' moral distress. SUMMARY BACKGROUND DATA: Moral distress experienced by clinicians can lead to low-quality care and burnout. Older adults increasingly receive invasive treatments at the end of life that may contribute to surgeons' moral distress, particularly when external factors, such as pressure from colleagues, institutional norms, or social demands, push them to offer surgery they consider non-beneficial. METHODS: We mailed surveys to 5200 surgeons randomly selected from the American College of Surgeons membership, which included questions adapted from the revised Moral Distress Scale. We then analyzed the association between factors influencing the decision to offer surgery to seriously ill older adults and surgeons' moral distress. RESULTS: The weighted adjusted response rate was 53% (n = 2161). Respondents whose decision to offer surgery was influenced by their belief that pursuing surgery gives the patient or family time to cope with the patient's condition were more likely to have high moral distress (34% vs 22%, P < 0.001), and this persisted on multivariate analysis (odds ratio 1.44, 95% confidence interval 1.02-2.03). Time required to discuss nonoperative treatments or the consulting intensivists' endorsement of operative intervention, were not associated with high surgeon moral distress. CONCLUSIONS: Surgeons experience moral distress when they feel pressured to perform surgery they believe provides no clear patient benefit. Strategies that empower surgeons to recommend nonsurgical treatments when they believe this is in the patient's best interest may reduce nonbeneficial surgery and surgeon moral distress.

Momentary predictors of dietary lapse from a mobile health weight loss intervention.

Identifying factors that influence risk of dietary lapses (i.e., instances of dietary non-adherence) is important because lapses contribute to suboptimal weight loss outcomes. Existing research examining lapse risk factors has had methodological limitations, including retrospective recall biases, subjective operationalizations of lapse, and has investigated lapses among participants in gold-standard behavioral weight loss programs (which are not accessible to most Americans). The current study will address these limitations by being the first to prospectively assess several risk factors of lapse (objectively operationalized) in the context of a commercial mobile health (mHealth) intervention, a highly popular and accessible method of weight loss. N = 159 adults with overweight or obesity enrolled in an mHealth commercial weight loss program completed ecological momentary assessments (EMAs) of 15 risk factors and lapses (defined as exceeding a point target for a meal/snack) over a 2-week period. N = 9 participants were excluded due to low EMA compliance, resulting in a sample of N = 150. Dietary lapses were predicted by momentary increases in urges to deviate from one's eating plan (b = .55, p < .001), cravings (b = .55, p < .001), alcohol consumption (b = .51, p < .001), and tiredness (b = .19, p < .001), and decreases in confidence related to meeting dietary goals (b = -.21, p < .001) and planning food intake (b = -.15, p < .001). This study was among the first to identify prospective predictors of lapse in the context of a commercial mHealth weight loss program. Findings can inform mHealth weight loss programs, including just-in-time interventions that measure these risk factors, calculate when risk of lapse is high, and deliver momentary interventions to prevent lapses.

Routine Maternal Vaccine Uptake during the COVID-19 Pandemic.

OBJECTIVE: This study examines the impact of the coronavirus disease 2019 (COVID-19) pandemic on influenza and tetanus toxoid, reduced diphtheria toxoid and acellular pertussis (Tdap) vaccine uptake in a pregnant, low-income population. STUDY DESIGN: This retrospective cohort study included women initiating prenatal care before (May-November 2019) or during the COVID-19 pandemic (May-November 2020) at two large Medicaid clinics. All patients entered prenatal care before 20 weeks and delivered full-term. Medical records were reviewed for vaccine uptake and demographic data. Multivariate logistic regression analysis was used to compare vaccination rates prior to and during the COVID-19 pandemic. Additional analysis was performed to identify association of demographic factors with vaccine uptake. IRB approval was obtained for this study. RESULTS: A total of 939 patients met inclusion criteria, with 462 initiating care prior to and 477 initiating care during the COVID-19 pandemic. Influenza vaccination uptake was 78% (362/462) in the prepandemic group, significantly decreasing to 61% (291/477) in the pandemic group (p <0.01, odds ratio [OR] = 0.38, confidence interval [CI]: 0.26-0.53). Tdap vaccination uptake was 85% (392/462) in the prepandemic group, significantly decreasing to 76% (361/477) in the pandemic group (p <0.01, OR = 0.56, CI: 0.40-0.79). The decrease in influenza vaccine uptake was most significant in non-Hispanic Black patients, decreasing from 64% (73/114) in the prepandemic group to 35% (35/101) in the pandemic group (p <0.01, OR = 0.30, CI: 0.17-0.52), while there was no significant difference in age or parity in relation to vaccination status. CONCLUSION: Routine vaccination uptake significantly decreased during the COVID-19 pandemic in a low-income population of pregnant women, with decrease more pronounced on influenza vaccine than on Tdap vaccine uptake, especially in non-Hispanic Black patients. KEY POINTS: · Influenza and Tdap vaccination uptake during pregnancy has decreased during the COVID-19 pandemic.. · Influenza vaccine uptake decreased more than Tdap in pregnancy during the COVID-19 pandemic.. · The greatest decrease was seen in influenza vaccine uptake in non-Hispanic Black patients..

Washable, Sewable, All-Carbon Electrodes and Signal Wires for Electronic Clothing.

Smart wearable electronic accessories (e.g., watches) have found wide adoption; conversely, progress in electronic textiles has been slow due to the difficulty of embedding rigid electronic materials into flexible fabrics. Electronic clothing requires fibers that are conductive, robust, biocompatible, and can be produced on a large scale. Here, we create sewable electrodes and signal transmission wires from neat carbon nanotube threads (CNTT). These threads are soft like standard sewing thread, but they have metal-level conductivity and low interfacial impedance with skin. Electrocardiograms (EKGs) obtained by CNTT electrodes were comparable (P > 0.05) to signals obtained with commercial electrodes. CNTT can also be used as transmission wires to carry signals to other parts of a garment. Finally, the textiles can be machine-washed and stretched repeatedly without signal degradation. These results demonstrate promise for textile sensors and electronic fabric with the feel of standard clothing that can be incorporated with traditional clothing manufacturing techniques.

Particle Property Characterization and Data Curation for Effective Powder Property Modeling in the Pharmaceutical Industry.

Computational modeling, machine learning, and statistical data analysis are increasingly utilized to mitigate chemistry, manufacturing, and control failures related to particle properties in solid dosage form manufacture. Advances in particle characterization techniques and computational approaches provide unprecedented opportunities to explore relationships between particle morphology and drug product manufacturability. Achieving this, however, has numerous challenges such as producing and appropriately curating robust particle size and shape data. Addressing these challenges requires a harmonized strategy from material sampling practices, characterization technique selection, and data curation to provide data sets which are informative on material properties. Herein, common sources of error in particle characterization and data compression are reviewed, and a proposal for providing robust particle morphology (size and shape) data to support modeling efforts, approaches for data curation, and the outlook for modeling particle properties are discussed.

Associations between fear of weight gain and exercise in binge-spectrum eating disorders.

PURPOSE: Maladaptive exercise (i.e., exercise that is either driven or compensatory) is thought to momentarily down-regulate elevated fear of weight gain (FOWG). However, little research has examined associations between FOWG and exercise, and no research has measured FOWG at a momentary level or considered exercise type (i.e., maladaptive vs. adaptive). Thus, we examined both within- and between-subject associations between FOWG and exercise among individuals with trans-diagnostic binge eating. METHODS: We recruited treatment-seeking adults (N = 58, 82.9% female) to complete a 7-14-day ecological momentary assessment protocol which assessed levels of FOWG and exercise engagement and type. Mixed models and generalized estimating equations assessed within-subject associations, and linear regression assessed between-subject associations. RESULTS: There was no main effect of FOWG on exercise engagement at the next survey. However, unexpectedly, exercise type moderated this relationship such that the relationship between FOWG and exercise was strongest for episodes of adaptive exercise. Overall exercise frequency accounted for 10.4% of the variance in FOWG and exercise type explained an additional 1.7% of the variance in FOWG. CONCLUSION: The findings of the current study indicate that momentary levels of FOWG are associated with subsequent adaptive exercise episodes, while higher overall levels of maladaptive exercise were associated with higher levels of FOWG. Future treatments should place a greater emphasis on reducing the frequency of maladaptive exercise by providing strategies for reducing FOWG. LEVEL OF EVIDENCE: Level IV: Evidence obtained from multiple time series analysis such as case studies.

Money Moves the Mare: The Response of Community-Based Organizations to Health Care's Embrace of Social Determinants.

Policy Points Health policies that encourage health and social integration can induce community-based organizations (CBOs) to adopt new ways of working from health care organizations, including their language, staffing patterns, and metrics. These changes can be explained by CBOs' perceptions that health care organizations may provide new sources of revenue. While the welfare implications of these changes are not yet known, policymakers should consider balancing the benefits of professionalizing CBOs against the risks of medicalizing them. CONTEXT: Recent health policies incentivize health care providers to collaborate with community-based organizations (CBOs), such as food pantries and homeless shelters, to address patients' social determinants of health (SDOH). The perspectives of health care leaders on these policy changes have been studied, but the perspectives of CBO managers have not. METHODS: Our research question was: How are CBOs in Massachusetts perceiving and responding to new Medicaid policies that encourage collaboration between health care organizations and CBOs? We interviewed 46 people in leadership positions at CBOs in Massachusetts for approximately an hour each. We analyzed these data abductively, meaning that we iterated between inductively coding transcripts and consulting existing theories and frameworks. FINDINGS: We found evidence of a knowing-doing gap among CBOs. Even though CBOs value their distinctiveness and autonomy from health care, they have undertaken a series of organizational changes in response to the new Medicaid policy that make their organizations appear more like health care organizations. These changes include adopting new performance metrics, hiring clinical staff to the board and senior management positions, and using medical language to describe nonmedical work. Drawing on institutional theory, we suggest that the nonprofits undertake such changes in an effort to demonstrate legitimacy to health care organizations, who may be able to provide new sources of critically needed revenue. CONCLUSIONS: Massachusetts CBOs perceive health systems as potential sources of revenue, due in part to an ongoing Medicaid redesign that encourages the integration of health and social services. This perception is driving CBOs to appear more like health care organizations, but the impacts of these changes on welfare remain unknown.

Healthcare lobbying on upstream social determinants of health in the US.

Healthcare stakeholders are increasingly investing to address social determinants of health (SDOH) as they seek to improve health outcomes and reduce total healthcare costs in their communities. Policy heavily shapes SDOH, and healthcare lobbying on SDOH issues may offer large impacts through positive policy change. Federal lobbying disclosures from the ten highest spending health insurance and healthcare provider organizations and related associations between 2015 and 2019 were reviewed to identify lobbying reported on the salient SDOH issues, defined based on the Accountable Health Communities Model health-related social needs screening tool. Five of the organizations reported lobbying on some SDOH issues, including financial strain, employment, food insecurity, and interpersonal safety, but none reported lobbying on other issues, such as non-healthcare-related employment, housing instability, transportation, or education. Lobbying has been a missed opportunity for addressing SDOH. Healthcare organizations have the opportunity to expand their lobbying on upstream SDOH policy issues to increase the impact of their SDOH strategy and further improve population health.

Memory rehabilitation for people with multiple sclerosis.

BACKGROUND: Problems with cognition, particularly memory, are common in people with multiple sclerosis (MS) and can affect their ability to complete daily activities and can negatively affect quality of life. Over the last few years, there has been considerable growth in the number of randomised controlled trials (RCTs) of memory rehabilitation in MS. To guide clinicians and researchers, this review provides an overview of the effectiveness of memory rehabilitation for people with MS. OBJECTIVES: To determine whether people with MS who received memory rehabilitation compared to those who received no treatment, or an active control showed better immediate, intermediate, or longer-term outcomes in their: 1. memory functions, 2. other cognitive abilities, and 3. functional abilities, in terms of activities of daily living, mood, and quality of life. SEARCH METHODS: We searched CENTRAL which includes Clinicaltrials.gov, World Health Organization (The Whoqol) International Clinical Trials Registry Portal, Embase and PubMed (MEDLINE), and the following electronic databases (6 September 2020): CINAHL, LILACS, the NIHR Clinical Research Network Portfolio database, The Allied and Complementary Medicine Database, PsycINFO, and CAB Abstracts. SELECTION CRITERIA: We selected RCTs or quasi-RCTs of memory rehabilitation or cognitive rehabilitation for people with MS in which a memory rehabilitation treatment group was compared with a control group. Selection was conducted independently first and then confirmed through group discussion. We excluded studies that included participants whose memory deficits were the result of conditions other than MS, unless we could identify a subgroup of participants with MS with separate results. DATA COLLECTION AND ANALYSIS: Eight review authors were involved in this update in terms of study selection, quality assessment, data extraction and manuscript review. We contacted investigators of primary studies for further information where required. We conducted data analysis and synthesis in accordance with Cochrane methods. We performed a 'best evidence' synthesis based on the methodological quality of the primary studies included. Outcomes were considered separately for 'immediate' (within the first month after completion of intervention), 'intermediate' (one to six months), and 'longer-term' (more than six months) time points. MAIN RESULTS: We added 29 studies during this update, bringing the total to 44 studies, involving 2714 participants. The interventions involved various memory retraining techniques, such as computerised programmes and training on using internal and external memory aids. Control groups varied in format from assessment-only groups, discussion and games, non-specific cognitive retraining, and attention or visuospatial training. The risk of bias amongst the included studies was generally low, but we found eight studies to have high risk of bias related to certain aspects of their methodology. In this abstract, we are only reporting outcomes at the intermediate timepoint (i.e., between one and six months). We found a slight difference between groups for subjective memory (SMD 0.23, 95% CI 0.11 to 0.35; 11 studies; 1045 participants; high-quality evidence) and quality of life (SMD 0.30, 95% CI 0.02 to 0.58; 6 studies; 683 participants; high-quality evidence) favoring the memory rehabilitation group. There was a small difference between groups for verbal memory (SMD 0.25, 95% CI 0.11 to 0.40; 6 studies; 753 participants; low-quality evidence) and information processing (SMD 0.27, 95% CI 0.00 to 0.54; 8 studies; 933 participants; low-quality evidence), favoring the memory rehabilitation group.  We found little to no difference between groups for visual memory (SMD 0.20, 95% CI -0.11 to 0.50; 6 studies; 751 participants; moderate-quality evidence), working memory (SMD 0.16, 95% CI -0.09 to 0.40; 8 studies; 821 participants; moderate-quality evidence), or activities of daily living (SMD 0.06, 95% CI -0.36 to 0.24; 4 studies; 400 participants; high-quality evidence).  AUTHORS' CONCLUSIONS: There is evidence to support the effectiveness of memory rehabilitation on some outcomes assessed in this review at intermediate follow-up. The evidence suggests that memory rehabilitation results in between-group differences favoring the memory rehabilitation group at the intermediate time point for subjective memory, verbal memory, information processing, and quality of life outcomes, suggesting that memory rehabilitation is beneficial and meaningful to people with MS. There are differential effects of memory rehabilitation based on the quality of the trials, with studies of high risk of bias inflating (positive) outcomes. Further robust, large-scale, multi-centre RCTs, with better quality reporting, using ecologically valid outcome assessments (including health economic outcomes) assessed at longer-term time points are still needed to be certain about the effectiveness of memory rehabilitation in people with MS.

The profile of pragmatic language impairments in children with ADHD: A systematic review.

This systematic review synthesizes the empirical literature examining pragmatic language in children diagnosed with attention-deficit/hyperactivity disorder (ADHD). Using a taxonomy of pragmatic language, we compared the pragmatic language profiles of children with ADHD to those of typically developing (TD) children and children with autism. Three databases were searched up to October 2019: PsychInfo; PubMed; and CSA Linguistics and Language Behavior Abstracts. We included 34 studies reporting on 2,845 children (ADHD = 1,407; TD = 1,058; autism = 380). Quality and risk of bias assessments included sample size and representativeness; measure reliability and validity; and missing data management. Children with ADHD were found to have higher rates of pragmatic difficulties than their TD peers. Specific difficulties were identified with inappropriate initiation, presupposition, social discourse, and narrative coherence. Children with ADHD appear to differ from those with autism in the degree of their pragmatic language impairments. General language skills contribute to, but do not explain, pragmatic difficulties in samples of children with ADHD. Though the extant evidence is limited, a preliminary profile of the pragmatic language impairments in children with ADHD is indicated. This supports a call for evidence-based interventions that include pragmatic language skills training.

Perovskite-Carbon Nanotube Light-Emitting Fibers.

Active fibers with electro-optic functionalities are promising building blocks for the emerging and rapidly growing field of fiber and textile electronics. Yet, there remains significant challenges that require improved understanding of the principles of active fiber assembly to enable the development of fiber-shaped devices characterized by having a small diameter, being lightweight, and having high mechanical strength. To this end, the current frameworks are insufficient, and new designs and fabrication approaches are essential to accommodate this unconventional form factor. Here, we present a first demonstration of a pathway that effectively integrates the foundational components meeting such requirements, with the use of a flexible and robust conductive core carbon nanotube fiber and an organic-inorganic emissive composite layer as the two critical elements. We introduce an active fiber design that can be realized through an all solution-processed approach. We have implemented this technique to demonstrate a three-layered light-emitting fiber with a coaxially coated design.
